AOS’s Material and its Characteristics
A rubber part is used in various situations, so the choice of the material
is important. We prepared various types of rubber in addition to the general
specified material in JIS and JASO. The following compounds are some of
the representative materials which AOS developed. AOS also has the other
types of materials too, so please feel free to consult on us about your
request of the physical and chemical properties of rubber. We’re also welcome
to develop a new type of material based on your requirements. We develop
and hold the materials normally based on the specification programmed by
Japanese organizations, but we also welcome to develop the material based
on other standards, for example, ISO, ANSI or Mil spec. Please give us
your spec. by ASTM callout.
| Type | AOS Material No. | Rubber Type | Characteristics | JIS B2401 |
|---|---|---|---|---|
| General Material |
AN7003B | NBR | Most representative material in AOS Resistance to heat ageing, oil, and abrasion | 1-A |
| AN9004B | NBR | Similar physical proerties to AN7003B in addition to the resitance to high pressure and abrasion | 1-B | |
| AN7030B | NBR | Resistance to heating oil and light oil | 2 | |
| AE7004B | EPDM | Resistance to plant oil, for example brake oil and coolant Resistance to weathering and ozone Insulation characteristics |

| AS7011B | Si | Resistance to heat ageing and low temperature AS7011B can be used in the broad range of temperature condition | 4-C | |
| AF7004B | FKM | Resistance to oil, heat ageing, and wide range of chemicals | 4-D | |
| AA7001B | ACM | Superiority to NBR in the resitance to heat ageing Resistance to brake oil and gear oil | 4-E※ | |
Special Material |
AN7006B | NBR | Expaneded graphite is included in AN7006B. This NBR is expanded in the high temperature condition and effect the heat-retention, heat insulation and the resistance to flammability | |
| AN7008B | NBR | High performance in the resistance to gas within NBR | ||
| AN7036B | NBR | High performance in the resistance to low temperature within NBR | ||
| AHN7009B | H-NBR | Most major H-NBR in AOS Superiority to the normal NBR in the resistance to heat ageing, oil, abrasion, tear, and wethering. | ||
| AF7006B | FKM | More Excellent perfromance than the normal FKM in the resistance to the chemicals and solvents | ||
| AF7021B | FKM | The same level of resistance as AF7004B to heat ageing and chemicals in addition to the high performance in low teperature condition |
※4-E is Standard Material for JASO F404
